AbilityTask_NetworkSyncPoint can cause duplicate Gameplay Effect applications

A recent change to UAbilityTask_NetworkSyncPoint generates a second Prediction Key before broadcasting the OnSync delegate which may be preventing the server from removing the locally predicted GE

• Create an ability
• Add a Wait Net Sync ability task node to Event ActivateAbility
• Add a ApplyGameplayEffectToOwner node to the OnSync delegate pin of the Net Sync task
• Activate the Ability in multiplayer PIE
• Note that the GE is applied twice on the client
